6 Claims. Cl. 242-56) This invention relates to web winding and more particularly to a method of and means for forming successive rolls of predetermined size from a continuously moving Web.

It is a general object of the present invention to provide a novel and improved method of winding a continuously travelling web into a succession of rolls, and to provide novel apparatus for effectively carrying out the method.

More particularly it is an object of the invention to provide both method and apparatus for handling a continuously travelling web and forming it into successive rolls of desired size, alternately formed on adjacent winders, together with means for transferring the web from the active winder to a prepared web leader on the other and means for severing the web feeding to the active winder whereby it may follow said leader to be wound on the other winder.

An important object of the invention resides in the arrangement for continuous winding from a. travelling web successive ro'ls formed alternately on one of a pair of adjacent, parallel, two-drum, surface-winders together with means to prepare for and transfer the winding from the winder on which the roll is reaching maximum desired size to the other or idle winder without stopping the movement of the web.

Another object of the invention resides in theme of a leader threaded onto the idle winder and prepared with an adhesive end to be pressed against the Web travelling to the active winder to adhere thereto, then starting the threaded winder and automatically severing the web between the point of adhesion and the active Winder whereby the web is diverted to the newly started winder.

Still another object of the invention resides in-the arrangement whereby a fixed and a pendulum roller on opposite sides of the path of the web being wound may be brought together to cause adherence between the adhesive-coated end of a leader fed over either of the rollers and the travelling web.

A further object of the invention resides in the arrangement of apparatus whereby the severing of the web between the adhesive joint and the active winder is initiated by the joint advancing toward the active winder.

A still further object of the invention consists in an arrangement of apparatus for-automatically powering the inactive winder and depowering the active winder by the manual operation of advancing the movable roller toward the moving web to produce the adhesion of web and leader.

Other and further objects and important features of the invention will be more apparent to those skilled in the art upon a consideration of the following specification and accompanying drawings wherein. is disclosed a single. exemplary embodiment of the invention, with the understanding that such changes and modifications may be made therein as fall within'the'scope of the appended claims without departing from the spirit of the invention.

Fig. 1 is a perspective'view of a single, two-drum, surface winder of the type used in duplicate in the present invention;

Fig. 2 is an end elevation of a continuous winding machine using dual drum winders constructed in accordance with the present invention, shown winding :1 roll on the left winder and with the right winder prepared to start winding;

'Fig. 3 is a view similar to Fig. 2 but showing the alternate condition of the two winders;

Fig. 4 is an end elevation of the switch arrangement for controlling the power clutches of the two winders;

Fig. 5 is a side elevation of the splice detector and switch actuated thereby; and

Figs. 6 and 7 are diagrammatic representations of the lead of a web onto its bundle in two-alternative arrangemachines as coacting, embossing and laminating devices, impregnating machines, flexographic and aniline printers,

rotogravure and printing presses-and the like. Since these devices preferably operate on a non-stop basis the web is continuously delivered at a uniform velocity and it is usually desired to wind it into bundles of predetermined lengths or diameters without the necessity for stopping the web advance and devices have been suggested for handling these outputs and transferring the web from one winder to another. The present invention seeks to improve and simplify winders and to provide for continuous operation in the formation of rolls without the need for stopping the treated web.

Fig. 1 illustrates, more or less schematically, the construction and operation of a two-drum surface winder which consists primarily of a pair of similar, journalsupported and laterally spaced drums 10 and 11 of substantially the same diameter and driven in the same direction, as indicated, through either a chain and sprocket arrangement as illustrated at 12 or by an interconnecting gear train. In practice, where the chain system is used to transfer power, one drum is generally a few thousandths of an inch larger in diameter than the other one to impart to it a faster circumferential speed.

The web may be wound on a cylindrical mandrel 13 resting on the surfaces of the two rolls and preferably weighted with a steel shaft 14, or the like, to provide adequate winding contact, but can be wound into a hollow bundle using a weighted shaft loosely positioned therein during starting. The web may be threaded onto the winder in several alternative manners, but generally in such a fashion that it is in contact first with the drum having slower circumferential speed. The larger drum due to the extra pull it exerts on the web, by virtue of its greater circumferential speed, tends to keep the web tight at all times as it winds onto the mandrel. One or both of the drums may have splaying grooves on their surface disposed as shown at 15 on drum 11 in order to stretch the web laterally and avoid the formation of wrinkles or creases therein. This type of winding device is of extreme simplicity and requires no speed changers or the like and produces a tight satisfactory roll but has heretofore offered difficulty when roll change became necessary.

Figs. 6 and 7 showtwo methods of threading web W into the winder. In'Fig. '6-web froma treating or manu- I it spread lat ends in the frame endmembers.

The'two winders Aand B arearranged with their axes parallel and spaced apart as suificient distance to .freely accommodate vertical standards 20, onelextending .upwardly from each end of frame 18 and preferably connected together at the top (not shown) for rigidity andreinforced with gussetsv at 21 near the bottom for the same purpose. V

On transverse vertically separated platforms 22 and23 on one standard 20 are mounted the drive motor 24'with its integrated reduction gear 25 on the upperone and on; thelowerthe pair of clutches 26. and 27." The driving membersof the clutches are connected by suitable chains or similar means 28 to twin sprockets on the shaft 'of the speed reducer 25, and the driven portion of each clutch is connected by a chain 30 to a sprocket on one of ther- 7 drums of a winder, the two drums of eachwinder being connected together and sized as in "Fig. 1. The clutches 26 and 27 are electromagnetically operated as 'will be further explained. a V p Near their tops the standards 20' support horizontal" 1 lead roll 32 which-takes the web W continuously .supplied to it from any suitable mechanism and directs it vertically downwardly, betweenthe standards,.as shown 7 indash lines, to either the right diverter roll 33 in the manner illustrated in Fig. 3,

asin'Fig.2. V

Fromthediverter roll 33, in Fig;'3 the web is fed to the 80 'undersidei of and partly around drum 11 of winder B from which it -is;wound onto the mandrel 13in a clockwise direction in the manner illustrated and explained in connection withFig. 7. When, however, the web passes about diverter roll 34 it moves horizontally beneath drum 10 of winder'A and passes around direction-reversing roll or to the left diverter roll 342-.

7 35 from which it follows the same path around drum 11 of this winderas explainedin connection with winder.B.. The diverter and reversing rolls are journalled; at their In Fig. 2 it is seen that from guide roll 32v web W passes closely adjacent the surfaces of horizontal pressure "mus 36 and'37 one mounted'slightly above the other at" .the left edges ofstandards 20 intermediate the position ofthe "motonpla'tform'and guide run 321 Opposite to these is the suspendedpendulum roll 38 supported by 'links 39 to which it. is pivoted for rotation. These links are connected to a shaft johrnalled in blocks 40' on the standards and having the "manual operating lever 42 whereby the pendulum roll may be swung in a clockwise direction toward the faces/of pressurerolls 36 and 37.

Beneath the .rolls 3.6, 3.7, and,38 ar e the oppositely disposed platforms 43. and.44, carried by the standards and each having a horizontal portion as well as an inclined :portion' 45 or 46. Brace members are shown supporting -the outer'edges of the horizontalportions.

In Fig. 2 thelweb pas ses downwardly over guide roll 32 and then horizontally from diverter roll 34, around reversing-roll 35,; about-drum 1 1, about the web wound on mandrel 13 and continues to buildup the bundle being formed on winder A. a Beforethis 'roll approaches the desired maximum size, which may be determined either by using a measuring device to indicatezthe number of yards of webthereonfor by measuring its overall diameter, the apparatusis prepared toreceiye and transfer the web' onto winder B in the following manner. A length of A waste web orspecial web pre'paredas a leader L is wound Several times ;by hand about mandrel or into a loose roll overa weighted shaft which isthen positioned, as shown, 'on the drums of winder B, the web leader then passed down between the drums, around diverter roll 33, up between standards .20, over pendulum roll 38 and its end positioned on the inclined portion 46 of the right platform where its upper surface is coated, as shown at 50, with a suitable'adhesive such as rubber cement which dries with a tacky surface.

Clutch 26 remains engaged to continue to drive winder A while clutch 27 remains disengaged so that no movementof thev drums of winder B takes place. As the bundle being formed on winder A reaches its desired maximum size the operator pulls down manually on lever 42moving the pendulum roller and its supported leader L against the traveling web and both web and leader are urged against the pressure rolls' 36 and" 37. I The link 51. attached to lever 42 operates .plunger152 to close switch 53, simultaneouslywith movement of the, pendulum roll, whereby clutch 27 is energized and the drums of winder B start movement to pull the leader along with the web so that both pass between the pressure rolls .and the pendulumroll and when the adhesively coated end of the leader makes this passage it is properly and strongly adhered to the surface of the web, which, it will beremernberecL'is traveling at the same rate of speed as the leaderbecause therates of speed are determined by the similar surface speedsof similar drums 10. a The web and the leader move downwardly together,

a one winding on the roll'on winder A and the other on the winder B. When thefadhered portion passes .below shelf 23 it engages the operator of switch. 55 mounted on'the inner faceof one. standard 20 and closes the circuit'to the. electromagnet 56 of paper severing mecha- 'nism 57 associatedwith'winder. A whereupon the serrated knife .blade 58 is lifted and severs the web W between rolls 34 and 35. The switch operating clutch 26 for .the winder A may either now be released or could have been disengaged simultaneously with the closing of switch 53, for the momentum of the large bundle on winder A would carry it over' several times to complete the operation of winding from the time of the adhesive contact until the torn end of. theweb is wound on the roll.

At the time of web severing the leader takes control of the remainder of the web, to which it is attached, draws it about roll 33, beneath drum ll of winder B and starts winding'it on the mandrel of that winder following the already started leader. Any portion of the webbetween the junction'with the leader and the place where it was cut is merely folded back and doubled up harmlessly onflthe ins ide of thebundle forming on hw n ir at vin f= r a Referring now to Fig. 3, it will be noted that the transferred web has about completed the bundle on winder B and a leader L has been started on mandrel 13 of winder A, passed about rolls 35 and 34 and over pressure roll 36 and onto table 45 where its end has been coated as at 50 with a suitable adhesive in the same preparatory manner as explained in connection with the leader intended to feed to winder B. In the meantime the shell 60 which guides plunger 52 actuated by link 51 connected to handle 40 has been transferred in position from switch 53 to switch 61 so that when the appropriate time arrives to make the transfer the handle is again drawn down and pendulum roll 38 is forced first against the web W and presses it in contact with the leader L spanning rolls 36 and 37 at which time switch 61 is closed and clutch 26 energized to start winder A which begins to pull the leader 1. downwardly until the adhesive portion 50 is brought into contact with the web between the pressure rolls and the pendulum roll, and adhesion is eifected.

From hereon the operation is the same as in the preceding arrangement, the switch 55, however, having now been arranged to activate the magnet 62 of paper severer 63 whose knife 64 now cuts the web between diverter roll 33 and drum 11 of winder B allowing the leader L directed to winder A to take control of the web which is drawn over and wound on winder A to the desired size.

Fig. 4 illustrates the arrangement of the pair' of switches 53, 61 on their shelf 65, which control, respectively, the operation of clutches 27 and 26 for driving the respective winders. Here the shelf is shown supported from standard 20 and having in alignment thereon the switches 53 and 61. A guide plate 70 extends upwardly from the shelf edge and supports the traveling shell 60 whose depending edge 72 may be guided along the surface of the shelf, if desired, and this shell 60 mounts collar 73, which guides plunger 52 having the inclined inner end 75, adapted when pressed downwardly to actuate plunger 76 of switch 61 and close the circuit thereof.

The link 51 having the bifurcated upper end 77 is arranged to be actuated by lever 40 as previously explained. The shell carrying the switch actuator is manually adjustable from the position shown in Fig. 2 where it co-operates with switch 53, to that shown in Fig. 3, transferring its control to switch 61. The switches 53 and 61 may be of the type that when momentarily closed by movement of the lever 40 and the actuating plunger 52 remain in the closed position until tripped manually by pushing button 78 thereon. The switch 53, not seen in Fig. 4, is identical with 61, shown there, but is connected to magnetically actuated clutch 27 instead of 26.

In Fig. 5 is illustrated the arrangement of the switch 55 actuated by means of the adhered junction of the web and the terminal end of the leader shown, respectively, at W and L. The switch is shown as supported by a bracket from standard 20 and having projected upwardly from the far end of the body an actuating plunger 80 capable of making only momentary contact. A lever 81, hinged at 82 to the opposite edge of the upper surface of the switch body has a hinged extension 82 which can be manually retracted, or thrown to the position illustrated so as to be pulled downwardly as the junction of the web and leader engage its upper surface, to close the switch and actuate the selected one of the web cutters shown at 57 and 63, respectively. While not illustrated it is obvious that a two-position switch must be arranged to transfer the control of web actuated switch 55 to either the magnet 56 or 62.

With the above explanations the operation of the apparatus for successively winding rolls or bundles of a desired size alternatively on one or the other of a pair of adjacent drum type surface winders from a continuously supplied web without stopping the latter will be entirely clear. It will be noted that the whole operation requires only the attention of an operator for a few moments in arranging the leader on the winder from which a filled roll has just been removed and in then effecting the transfer by momentarily actuating the handle 40.

We claim:

1. The method of winding successive rolls from a continuously travelling web comprising, guiding said web along a path and onto a weighted winding bundle, supporting and rotating said bundle by direct contact with the surface layer of web thereon, preparing a stationary second bundle with initial turns of a web leader, positioning the terminal portion of said leader adjacent said path and preparing its facing end with adhesive,'rotating said second bundle at at least the same peripheral speed as the speed of the said travelling web, pressing the terminal portion of said leader against the travelling web in said path with sufficient pressure to attach it thereto by said adhesive, and severing the web between said adhered portion and the first bundle.

2. The method of winding successive rolls from a continuously travelling web comprising guiding said web along a path from a source of supply and onto a winding bundle, supporting and rotating said bundle by direct contact on the outer layer of web thereon with a pair of driven rolls, winding initial turns of a web leader into a second bundle and positioning it on a second pair of rolls, applying adhesive material to a terminal area of said leader and positioning said area facing and adjacent said path, rotating said second bundle to a peripheral speed similar to that of the travelling web, adhering said area to the travelling web subsequent to rotating the second bundle, detecting a position of the joined web and terminal area and using the detection to sever the web between the first bundle and the detecting position.

3. The method of claim 2 in which a third bundle is prepared with a web leader and replaces the first bundle, applying adhesive to the end of said last-mentioned leader, and when the second bundle is filled, repeating the adhering and cutting for a continuous operation.
